PROBLEM TO BE SOLVED: To provide a method for producing a DDR type zeolite membrane-containing body wherein crack occurrence in the DDR type zeolite membrane and remaining of 1-adamantaneamine in the DDR type zeolite membrane are reduced. SOLUTION: The method for producing the DDR type zeolite membrane comprises a membrane formation step of immersing a porous substrate, having a DDR type zeolite seed crystal adhered thereon, in a raw material solution containing 1-adamantaneamine, silica (SiO<SB>2</SB>), and water to conduct a hydrothermal synthesis of DDR type zeolite to form a 1-adamantaneamine-containing DDR type zeolite membrane on the porous substrate to produce a precursor of DDR type zeolite membrane-containing body; and a burning step of heating the precursor at 400 to 550°C to burn and remove the 1-adamantaneamine contained in the DDR type zeolite membrane.
